Method 1: AntennaAdvisor Handle
You can use the Antenna Advisor handle. Make sure you initialize AntennaAdvisor first
to get more accurate directional information.
1
Press and hold the TRIGGER button on the handle and pan the antenna handle
to scan through until you find the strongest RSSI value.
RSSI, polarization, elevation, and azimuth readings are continuously updated on
the screen while pressing the physical button.
2
Release the TRIGGER button to stop scanning.
Method 2: Degree bar
The Degree Bar functions as a compass. You can use it to set azimuth by moving it
right and left.
Tap the circle on the Degree bar and move it gently until you get the right azimuth.
Method 3: Log-periodic antenna
You can use the log-periodic antenna.
Pan your log-periodic antenna to find a signal with the highest RSSI value and measure
an azimuth of the interfering signal.
To save the defined position
1
Tap any point on the map where you want to save the position information.
2
Tap the Save Position icon.
The instrument stores the saved location points in the internal memory, allowing
you to load them by using the Load Position icon. You can save and load up to
10 positions.
Setting display mode
When the triangulation is done with three location points and azimuth for each point,
you can view a circumscribed circle by default. You can change the display mode to
inscribed circle or double circles to view a narrower area. The center of the green-
shaded circle is determined to be where the source of the interfering signal resides.

NOTE
The AntennaAdvisor has a built-in low-noise amplifier (LNA) that can be turned
on and off using the physical On/Off button located on the rear side of the han-
dle unit. For example, if the received signal is weak, you can turn on the switch
to improve S/N.
